Description

In #18037, it was decided to add this to the deprecation timeline under 2.0: "ssi and url template tags will be removed from the future template tag library (used during the 1.3/1.4 deprecation period)."

At this time, it appears unlikely (from the discussion I've come across) that Django will have a "2.0" in the sense of a major backwards incompatible release in the foreseeable future. Thus, I think having this on the deprecation timeline may create some confusion. If we want to keep it, I think we should at least add some clarifying text as to what "2.0" means.

Looking back at the ticket I have to say, I think I still believed that a Django 2.0 would eventually be a API breaking release as Python 3. Now that we know how hostile that has been to Python I think we should reconsider this and use a proper deprecation roadmap.

I also would rather not use those poor template tags for creating a precedence of deciding what 2.0 means -- it's a much bigger discussion and shouldn't bound to bad decisions of the past. Let's move the deprecation into 1.9 and be done with it.
